Privacy Policy for QuantumShelf

Last Updated: November 29, 2025

Introduction

QuantumShelf ("we", "our", or "the app") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our inventory management application.

Information Collection and Use

Camera Permission

Purpose: QuantumShelf requests camera permission to enable barcode and QR code scanning functionality for adding and managing inventory items.

Data Handling:

• Camera images are processed locally on your device
• No photos or camera data are stored, transmitted, or shared
• Camera access is only active when you explicitly use the scanning feature
• You can deny camera permission and still use the app with manual item entry

Local Data Storage

The app stores the following data locally on your device:

• Inventory items (names, quantities, expiration dates, locations, etc.)
• Custom categories and locations
• Item history and transaction logs
• App settings and preferences

Important: All inventory data is stored locally on your device and is not transmitted to our servers.

Dropbox Sync (Optional)

If you choose to enable Dropbox synchronization:

• Your inventory database is synced to your personal Dropbox account
• We do not have access to your Dropbox account or data
• Sync occurs through Dropbox's official API using OAuth 2.0 authentication
• You control what data is synced and can disable this feature at any time
• Data transmitted to Dropbox is protected by Dropbox's security measures

Internet permission is used solely for:

• Dropbox synchronization (if enabled by you)

Third-Party Services

Dropbox (Optional)

Data Security

• All data is stored locally on your device using encrypted SQLite database
• Dropbox sync uses industry-standard OAuth 2.0 authentication
